` Specification of Letters Patent No. 12,877, dated May 15; 1855.

` To all whom t may concern Be it known that we, J THOMPSON,

J THOMPSON, and H. Q. THOMPSON, all

ofI-Iolderness, in the county of Grafton and State ofNew Hampshire, have invented a certa-inpnew anduseful Machine fo-r Polishing the Soles of Boots and Shoes,fand`that `the `following description, taken in conneo tion with the accompanying drawings, hereinafter `referred to, forms a full and exact specification of the'same, wherein `we have i fset forththe nature and principles of our said invention, by which it may be distinguishedfroni others of a similar class, tO- gether with such parts as we `claim and desiretohave secured to us by Letters Patent.

The `figures ofthe accompanying plate of drawings represent our improvements.

Figure l, is an end elevation of our machine. Fig. 2, is al `plan or top view Of the same. Fig. 3 isavertical section taken in the plane of the line A, B, Fig. 2.

The soles ofboots and shoes have heretoi "fore been polished or boned entirely by hand labor. `Ourmachine is designed to aecomplish this work, with much less expense and with greater rapidity, more than double the amo-unt of work` being accomplished in the same time by themachine than by hand.

The most` essential features Of our ma-` chine, consists of two bone polishers, at-

tached to a reciprocating shaft, which de-` rives its motion from two other parallel sole uppermost, againstY al bone` polisher, which polishes the main portion o-f the sole,

i y the part of the shank near the heel, being same shaft as the first` bone. 4:0`

polished by` another bone, attached to the a ain the drawings, represents` the sup,-

porting framework `of the machine.

wheel, to;` which is eccen-` ZJ isla `driving tri-cally attached, a `connecting rod '0, at-

tached toa shaft ,-which has its bearings in the standards exc. To one end of the shaft d ol, ``is connected the shaft 727, which carries the bone polishers g and hy lthe former being placed `at right angles Vto the i i shaft, f f,and thelatter in a longitudinal position on the underside of the same. By means of the driving wheel b, and shafting as described, it will readily be seen that a quick `reciprocating motion will be given to the bone polishers g and it, the triple shafting serving to prevent all jar, and giving a regular and uniform motion to the polishers. The shaft f .f passes through a standard ir so as to move up and4 do-wn in th'e same. The boot or shoe is held with its sole uppermost against the first polisher g, which by its motion polishes the greater portion of the sole. The boot or shoe is then turned, and held in such a. manner, as to bring the portion of the shank near the heel against the second polisher 72 which polishes the part ofthe sole near the heel that cannot readily be reached by the first polisher. The shaft f, while the sole is pressed against the bones, bears against a cross bar 7s, attached to a `sliding frame Z, Fig. 1. The frameZ bears at the bottom against a spiral spring m. By this arrangement the shaft f f can play up and down in the standard z' il, and by the force of the spring m, will cause the polishers to bear down upon the sole with an elastic yielding pressure. The under part of the shaft f f rests upon a stud bearing 'n which abuts against a spiral spring 0 in the standard Z Z the spring resting against a piece or rest p. Thus the shaft f f has an elstic bearing on both its upper and under si es.

Having thus described our improvements we shall state our claim as follows.

What we claim as our invention and desire to have secured to us by Letters Patent isi l A machine for polishing the soles of boots o-r shoes havin a polisher or polishers made of bone or otfier proper material attached to a shaft which has a reciprocating motion i
